Title: Improvement in a filter press
IPC: B01D25/172
Filed: 1958-04-29
Abstract: 845,330. Filter presses. KURITA, K. April 29, 1958, No. 13619/58. Class 46. A filter press comprises alternate filter plates 24, Fig. 1, and filter frames 27 in which the frames 27 are mounted slidably on side rods 28 while the plates 24 are mounted slidably on rods 25. The rods 25 are secured at either end to a connecting beams 23 which are each mounted on a pair of rams 21 at either end of the press. The side rods 28 are attached to heads 29, 29<SP>1</SP>, and the head 29 houses a scraper 53 secured to a lazy trap 46 which is actuated by a ram 50. Each frame 27 is provided at either side with lugs 30, Fig. 8, which are adapted for mounting the frame on the side rod 28, and have an upwardly opening notch 41 which is recessed at 41, and a bolt 42 screwed into the lug, the side opposite the bolt head being counterbored at 44. The filter plates 24 are also provided with lugs having bolts and notches in the reverse position as in Fig. 7 (not shown), i.e. the notch opens downwardly and the position of the notch and bolt is such that the bolt of the frame fits into the notch of the plate and vice-versa, thus when the ram 32, Fig. 1, is operated to act at the end plate 34 to close the press the bolt heads fit partially in the counterbore 44 of an adjacent similar element and when the ram is operated to open the press the bolt heads abut against the recess 41 1  of the notches of an adjacent element. In operation slurry is fed through an inlet 34 and passage way 35 in the plates and frames to the filter plates and the filtrate passes out through the lead 29 via similar passages (not shown). When due to clogging the slurry pressure rises a control is actuated to stop the supply of slurry and actuate the rams in the following sequence :- the ram 32 is actuated to separate the plates and frames, the rams are then actuated to lift the filter plates vertically to the position shown in dotted lines in Fig. 1 in which position the bottom of the filter plates still lie between the top of the frames, finally the ram 50 is actuated and the scraper 53 passes axially through the frames dislodging the filter cake which can fall between the frames. The control then actuates the rams to reverse this procedure and filtering continues.
